A G-SHOCK that fuses design with an shock-proof carbon core guard structure that uses a carbon case to protect the module.

Excellent upgrade for my EDC watch. Practical and very durable. Usually have to get a bigger size band when I buy a watch but this was fine for the G-shock. Might get a fancier GShock for after-hours but this is great for work and play. Happy to recommend

Very pleased with my first G-Shock watch. Looks good and feels tough and hard wearing. Straightforward to set up despite very small (and brief) instruction booklet.Delivery direct from Casio was very quick so overall customer service - including straightforward product registration - considered to be excellent.

Probably my most comfortable G-shock I own! Perfect size! Light weight, Yet still has that tough G-protection!Setting the time is super easy, And it's nice to see it self adjust to the World time.Best price I found this was at HS Johnson, And as always super fast Next day delivery and excellent customer service!
The watch arrived promptly and was very well packed . It felt lighter than I expected but it was robust and very smart. As this is a Christmas gift I was only allowed to look at it briefly but it functioned as advertised. I am looking forward to using it soon, counting the days!
I recently bought the GA-2000S-1AER watch as was looking for a more robust timepiece for work (I fabricate a lot of metalwork and operate a lot of machinery).Make no mistake, this is a quality watch however, the instruction manual supplied with it is so tiny, you need to use a magnifying glass to read it. Larger versions are available online but this is not a simple watch to set up in my opinion. The instructions need to be much clearer, offering a step by step guide (idiots guide?) to programme the watch. There were some instructions that felt like I was left hanging in mid-air. Needless too say that I could not work it out and so, am now in the process of making arrangements to return it for a full refund. A real shame as it is a very handsome looking watch and a ...

It is everything that I could expect it to be. Straight from the display to me in a nice box and served with politeness and all policies explained in a professional manner, extremely pleased with my purchase.

I was very please with my Casio G-Shock Carbon Core watch and with the very prompt service delivered by First Class Watches. Bravo!
Wonderful watch, great for everyday use.Very different to my other watches.
